Countervail

Then Esther the queen answered and said, If I have found favour in thy sight, O king, and if it please the king, let my life be given me at my petition, and my people at my request: For we are sold, I and my people, to be destroyed, to be slain, and to perish. But if we had been sold for bondmen and bondwomen, I had held my tongue, although the enemy could not COUNTERVAIL the king's damage. ( Esther 7:3-4 )

To thwart or overcome by acting against with equal force; thus, "The enemy could not countervail the king's damage" or loss (Esther 7:4 the American Standard Revised Version reads "The adversary could not have compensated for the king's damage"). "Nothing doth countervail (the Revised Version (British and American) "can be taken in exchange for") a faithful friend" (Ecclesiasticus 6:15).
